Application ruega v:gitaren "i My invention `relates to mechanism deobject to provide mechanism by vwhichfthis Y 3, and

l for shifting theV tools. y

A, A, indicate the base beams on which` Work can be `done with speed and accuracy. The naturek of my improvements will be best understoodas described in connection with the drawings in which they are illustrated and in which f Figure l is a sectional elevation of a bell mouth pipe and` of yaportion of the supporting mechanism also shown in section with a boring apparatus shown in side elevation and in place in thepipe. f Y

Figure 2 is an end elevation lshowing the bell end of the pipe, the mechanism for sup-- porting the pipe and the boring apparatus in position. l l l v Figure 3 is a sectional view onv the' line 3-#3 of Fig. l. A

Figure 4, a sectional view on the broken line P-4 of Fig. 8.

Figure 5 a view on the line 5-5 of Fig.

Figure 6 is a view'in part similar to Fig. l, but yshowing the boring tools .in a different position and the adjustable handle the pipe supporting apparatus rests. These beams are formed withl T shaped slots, as indicated at A1, and support the blocks B, B, which are adjustable along the beams A,r and are secured in desired positions by the bolts indicated at l), Z), etc. VThe blocks B are alternately flanged, as indicated at B1, B1, and support the cross bolsters indicated at C, C, which are secured to them by the bolts indicated at 0, c, etc., and which cross holsters are formed with l"`shaped slots, as indicated at C1, C1, and support in turn the pipe seats indicated at D, D, which are adjustably seciu'ed in place by means of bolts indicated at al, al. In order that the pipes may be firmly seated on these pipe seats, I provide in the lower central. portion of, each seat, an ad-v justable portion indicated at D1 which is adjusted and held in position by means of a bolt D2, as best shown in Fig; l.

Also adjustably secured on 'the cross bol-p' lsters C are theA heads indicated Aat- E, E', which are held in place in adjustable position by means .of the'bolts e, c, etc. and through which extend the bolts F1 with ad- 1, 1924.` seriai No. 698,432'.

indicated at F,

kG is thepipe having a bell end G1. in which va spherical socketis to be formed and which v 5 i pipe is secured on the pipe rests D by means' of the chains F, the adjustable parts 'in the supporting mechanism described being iintended to adapt this supporting mechanism for pipes of different size and also to make it practicable to adjust the .position of a vpipe into proper relationship with therdriven'v headfindicated at H, to which headkis securedvthe shaft H1 extending through. the pipe and supporting at its end, which extends into the bell of the pipe, theihead indicated at H2. The shaft yH1 is supported :in the pipeby the bearings I, I, which areiprovided with set screws, `as indicateol at I1, for properly adjusting them in the pipe and securing them, to the pipe. The shaft H1 is held against a lateral movement in its bearings, partly by the rings I2, I2, (see yright hand side of Fig. l) which is secured to the shaft by set screws 2 and which abut against theends of thejrighthand bearing I, and I make'still further provision for holding the shaft in against the right-*hand end of this-bearing I place a ring I5 which abuts against a series of adjusting screws i* in a ring I3 which is secured to the shaft H1 by the set screws indicated. at i3. 1

In the center of the head H2 formed at the end of the shaft H1, I secure a bearing pin J having annular rings J 1 J1 screwing upon its ends and preferably having the cap as indicated at J 2 for closing its end. The head H2 is forked, as best shown in Fig. 3, and, of course, its outer end is secured to the plate indicated at K which supports the bearing pin indicated at K1, upon which bearing pin is secured the gear wheel K2 having the crank handle K3 attached to it. This gear wheel is in engagement with the gear wheel K4 secured tov a shaft K5 having attached to its inner end a worm K6 which in turn engages the Worm wheel K7, having formed on or attached to it the worin indicated at K2 which in turn engages a Worm wheel segment `L1 attached to a rotating head L, supported atthe lend of the left hand `bearing I, while ,I

Vthreaded rods joui-nailed in the sleeve screwing,` in thethreaded sleeves tending arms L3, L3. Upon these arms are adjuster-bly secured the tool holding heads M, M, carrying tools indicated at Ml, and secured in adjusted positions by means o the bolts indicated at M secured. to one of the arms L3. rl`he upper one, as shown in Fig. 4, has the flanged plate lll carrylng,I an adjustable abutting` scren7 Ml in alignment with a lng` M on the upper tool holding head M, and by means of which a verynice adn eliecred, ll', ll, are sleeves secured to the head ll and lll, N, internally threaded sleeves secured to Athe iff; heads M, ld, N,

lll, connected together at their inner ends by a universal joint, indicated at N3.

' When it is desired to bore out a spherical Y socket in the pipe end CH, the pipe secured in its described supporting mechanism and brought lto proper alignment with the d ing head H; at the same time the shal carryingl its bearings l, l, inserted the pipe, nicely adjusted so that the bear lng pin J Will extend throusgli the center olf the spherical socket to be formed in the pi pe and the bearings l, l, are then .firmly secured in and to the pipe by means el the sere-r.v s ll and theshaft lg' is, oi course, attached the driving` `head l-l. rllhe tools Ml, M, are properly adjusted to cut the bell in the :when ical form desired and the shaft l-l is se in action and the proper contact olf the ools ellected by the rotation oit the cranl; ha e K3 which, through the mechanism descifibed,

mrd/lee spherical end of the pipe merges into theV cylindrical portion, a smooth junction should oe formed an d to eillect this When the head is swung to theV position indicated in Fig. 6, the tool, in what isthere the upper head M, is removed and the handle NL is attached to the end ofthe threadedrod N2 and turned so Y that the remaining tool M1 in the lower head M Will smooth oli the annular junction between the sphere and the cylinder, as indi-. cated in Fig. 6.

Having now described my invention, what l claim as new and desire to secure by Letters Patent, is: j

Mechanism for boring a spherical sockelJ in a pipe end comprising in combination a rotatable shalt having a head at. its end, a tool carrier pivoted on said'head so as to he adjustable in a plane parallel to the shaftA but not otherwise movable with referenceto tie shalt, said tool carrier having two voppositely extending tool supportmg arms, tool holders,adjustably supported on the arms oit the carrier, means for simultaneously ad? justmg the tool holders, and means for angularly adjlisting` the tool carrier on the head consisting or a Worm Wheel segment secinied y to the tool carrier and a Worm and gear train attached to the head` andincluding an actuating gear journalled at the end of the head for angular-ly adj zsting the tool carrier.
